build: explicitly list exported symbols in linker scripts

Before all symbols (global: *;) were exported, which included some
symbols that should not be exported. Update the symbol files to
exclude everything by default and name the exported symbols
explicitly.

Still the same symbols as before are exported.

    for SO in ./lib/.libs/*.so ./src/lib/.libs/*.so; do
        SYM="$(basename "$SO")"
        SYM="${SYM%.so}.sym"
        cat <<EOF | sed 's/^ *>> //' > "$SYM"
            >> libnl_3 {
            >> global:
            >> $(nm "$SO" | sed -n 's/^[a-fA-F0-9]\+ [BDRT] \(.*\)/\t\1;/p' | LANG=C sort)
            >> local:
            >> $(echo -e '\t')*;
            >> };
    EOF
    done
